APPARATUS FOR MTXING BBISTLE, HAIR, VEGETABLE FIBERS, AND THE LIKE.

Application filed May 13, 1825, Serial No. 30,107,'andin Germany September 27, 1924.

This iiivention relates to an apparatus for mixing bristles, hair, vegetable fibers and the like, the said mixing being elfected by folding the various layers of bristles over each other, after they have been manually intro; duced by the attendant into the apparatus at a supplying or feeding place in the form of single layers, for instance one behind another.

\ gether in the most uniform manner possi-' ble an in the shortest time, materials of different kind and nature, such as for instance bristles of different colour, bristles and hair together, bristles and Vegetable fibers together.

The-invention is'illustrated by way of example in the accompanying drawing in which Figure 1 shows diagrammatically in side elevation a mixing apparatus according to the invention;

Figure 2 is a section on line II-=II of Figure 1; I

Figure 3 is a diagram of a folding arrangement in a given construction of the apparatus;

Figure 4 shows diagrammatically a folding arrangement in another construction of the apparatus; and I Figure 5 shows diagrammatically in side elevation a modified construction of the apparatus.

According to the invention, on the machine frame therei's provided as a support a travelling conveyor band 0, and the bristles placed on the same by the attendant are delivered, with a given relatively low speed (in order to give the attendants time to put on), to pressure rollers d, (1. By these pressure rollers the bristles are held fast, and during the time of their passage through the said rollers, they are treated by a well known combing device. Behind the pressure rollers (l, d, are arranged fur ther pressure rollers e, e, f, f, g, g and so on. Between the said pressure rollers are arranged further conveyor bands i, is, Z, which supply or feed the bristles, with preferably increasing speed, to the next pressure rollers where they are again treated by combing devices. The bristles are finally delivered to a conveyor ban'dand are taken therefrom by the attendant.

The devices a to m represent the drawing denies, by means "or which the bristle layers The object of the apparatus is to mix to delivered in a given depth at 0, are pulled out and stretched. The conveyor band m carries the single bristle layers situated behind each other and stretched owing to the increase of their speed of advance,

to a delivery band A which reciprocates instance chains p, which pass over drums or:

chain wheels q and are reciprocated from any desired driving device C by changing the direction of rotation of the chain wheels 9 in the direction of the arrows n. The roller 0 is mounted between the said chains p, and between the latter is mounted another roller 1 over which the delivery band A is guided for the purpose of equalizing its length during the travel of the roller 0. Guide rollers s, t'and u are provided'for the same purpose.

The mixing band, B passes over guide rollers 11, w, w, *1, so that on a portion of its travel, it runs together with the conveyor band '0, and at this point carries the bristles from the bottom part of the machine upwards again.

The speed of the drawing device 0 to m,

as well as the speed of reciprocation of the chain p, and therefore the speed of travel of the roller 0- from its initial position to the point 0 and back again, can be cal culated, with reference to the speed of travel of the mixing band B for instance in such a manner that the delivery band A will place the layers of bristle on the mixing band B in a triple superposed layer, as shown in Figure 3. Y

In a particularly preferred construction, the speed of the said parts is however calculated in such a manner that the bristle strips are placed on the mixing band B in a superposed five-fold layer, as shown in Figure The bristle strips arranged in superposed triple or five-fold layer, are then carried upwards in that stratification by the mixing band B running together with the conveyor band 0, and delivered tothe conveyor band 0. These layers start then a ain to travel through the machine,- and 1n the case of the five fold stratifieatisa, the advantage ensured that the time required for complete mixing is relatively short.

An essential feature of the apparatus is that the point of delivery of the delivery band A which is formed in the roller 0, moves to and fro during the working of the apparatus, practically through the whole length of the apparatus, so that a long path is produced relatively to the length of the apparatus, and this long path contributes substantially to the good mixing of the single bristle layers, more particularly if the bristle materials have not been previously mixed by hand in a separate preparation stage, but single bristle layers of different nature are fed at the point of delivery of the apparatus in an irregular manner.

In the apparatus just referred to, the bristles are delivered as described through the delivery point constituted by the roller 0, to the mixing band B, the single bristle layers being folded in alternate directions. Consequently, the distance of the delivery band A from the mixing band B (height H) governs this delivery.

In the construction shown in Figure 5, this height H has been greatly reduced to a smaller height h, the delivery taking place over a fixed edge, instead of over a roller.

This apparatus comprises substantially the same parts as the apparatus described previously. There is provided a conveyor band 1, aressure rollers 2 to 9, intermediate conveyor bands 10 to 12 and a conveyor band 13, these parts corresponding to the drawing device 0 to m of Figure 1.

As in the apparatus previously described, there is here provided a mixing band 15, and the delivery device is also reciprocated in the direction of the arrows 16. The difference consists in the fact that the delivery device is constituted by a band 19 with a smooth surface, for instance a steel band, which is reciprocated by a gear chain 20 in the same way as the chains 39 of the apparatus in Figure 1. This band 19 has a dropping edge 21, and above it is arranged a travelling conveyor device 22 which travels in the direction of the arrow 23. This conveyor device could be constituted by a chain engaging over the bristles, and separate driver devices could be inserted be tween the single chain links. For delivering the bristles from the drawing device, to the delivery band 19, a guide device 24 is provided within the range of the conveyor band 13.
